I will work in Joules, then convert to calories.
q(Joules) = mass * specific heat * change in temperature C
q = (27.3 g Cu)(0.385 J/gC)(74.4o C - 36.2o C)
= 402 Joules (1 calorie/4.184 Joules)
= 96.1 calories

What is the percent of increase for 25 Celsius temperature to 1155 Celsius?
+4,520%
4 kg of ice at 0 degrees Celsius is converted to steam at 100 degrees Celsius How much heat is needed?
It takes 80 calories per gram to increase the temperature of water by one degree. 4000 * 80 * 100 = 32000000 calories.
Which is smaller increase in temperature a 5 Fahrenheit increase or a 5 Celsius increase?
A 5 degree Fahrenheit increase is less than a 5 degree Celsius increase
How much heat is required to raise the temperature of 3.5 grams of water from 12 degrees Celsius to 35 degrees Celsius answer in calories?
80.5 calories 35-12=23 23*3.5=80.5 1c raises 1 gr. h2o 1degree centigrade Here is the formula, it should help a lot:Total Number of Calories = (Specific Heat of Water) ×(Mass of Water) × (Absolute Temperature Change)
How many calories are required to raise 8 grams of water 7 degrees Celsius?
700
How were calories were made?
calories were never "made." they are simply the amount of energy required to raise the temperature one gram of water one degree celsius.
What is the total number of calories of heat needed to raise to raise the temperature of the liquid water from 20 degrees Celsius to 30 degrees Celsius?
The number of calories required will depend on the mass of water which is to be heated.
How much heat is required to increase the temperature of 203 grams of water from 20.1 Celsius to 51.3 Celsius?
2.65 x 10^4 J
What is the percent of increase for 25 Celsius temperature to 1155 Celsius?
+4,520%
4 kg of ice at 0 degrees Celsius is converted to steam at 100 degrees Celsius How much heat is needed?
It takes 80 calories per gram to increase the temperature of water by one degree. 4000 * 80 * 100 = 32000000 calories.
How many kcal required to increase temperature of 1 kg of water from 0 degrees Celsius to 10 degrees Celsius?
Since 1calorie=4.184jouels. Divide the 400g by 4.184j and you will get your answer as 96degress Celsius.
How many calories are required to increase the temperature of 13g of alcohol from 11 celsius to 23 celsius?
2.460 is the specific heat of ethyl alcohol in J/gC, so I will find joules and then convert to calories. q(joules) = mass*specific heat*change in temp. q = (13 g alcohol )(2.460 J/gC)(23 C - 11 C) = 383.76 joules (1 calorie/4.184 joules) = 92 calories ------------------
Which is smaller increase in temperature a 5 Fahrenheit increase or a 5 Celsius increase?
A 5 degree Fahrenheit increase is less than a 5 degree Celsius increase
How much heat is required to raise the temperature of 3.5 grams of water from 12 degrees Celsius to 35 degrees Celsius answer in calories?
80.5 calories 35-12=23 23*3.5=80.5 1c raises 1 gr. h2o 1degree centigrade Here is the formula, it should help a lot:Total Number of Calories = (Specific Heat of Water) ×(Mass of Water) × (Absolute Temperature Change)
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
Is a temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 59 degree Celsius correct or false?
correct
Why do you use Calorie instead of calorie?
A Calorie with a capital "C" is 1,000 calories with a little 'c'. Nutritional guides on food products measure Calories. A calorie is the amount of energy required to raise the temperature of one gram of water one degree celsius. Normally when you eat food it gives you energy. If you eat 1 Calorie of food, it is enough energy to heat one kilogram (2.2 pounds) of water one degree celsius. Jus to maintain your body temperature, you need to eat a lot of Calories. On the other hand, if you eat a 10 gram ice cube, your body has to raise the temperature of the ice from 0 degrees celsius to 37 degrees celsius (body temperature). You will burn 370 calories in the process, but that is only .370 Calories.
